Mmfp 1006 07 O Head Gasket Technology Half Inch Arp Studs

These are 1/2-inch ARP studs installed on an NMRA Pro Outlaw 10.5 engine. The studs help hold the head in place when this engine sees 40 psi of boost, courtesy of a ProCharger F3. We recommend adding head studs to most applications when you switch heads or change head gaskets often.
